Native plants from Argentina reported as effective against Leishmania spp.

Abstract

Leishmaniasis represents a spectrum of diseases caused by infection with protozoan pathogens of the genus Leishmania. It is a major neglected tropical disease associated with high rates of disability and death, with extended endemic areas in the Americas. Despite current therapeutic approaches, current treatments for leishmaniasis are unsatisfactory due to high associated toxicity, cost, complex administration and the emergence of resistant strains. Because of this, efforts have greatly increased over the last decade to identify novel compounds with anti-leishmanial properties. Thus, one strategy in the search for new compounds is the screening of molecules purified from plant sources. The current work reviewed the available information about the Argentinean natural sources reported as effective against Leishmania spp; including: its relevant chemical compounds, efficiency and applied methodology. Reported studies need to be considered as precursors works to extend the search between the profuse native plants from Argentina.
